Betty & Cody moving expenses an deposit

Hi my name is Betty I'm born and raised here in Miami never left, have never been in this situation before. My son's name is Cody I'm handicapped and my son is severely handicapped we are being forced to move suddenly because our landlord has sold the property we have until Feb 17th to be out of our house. We both live on our disability checks and have no other income. I have no money to move or money for a deposit for a new place nor money to pay people to help us move due to Cody's disabilities Down Syndrome, Autism,Non Veberal and OCD we cannot stay in a shelter he suffers from seizures , has behavior issues and wears diapers . I have tried several people we were recommended to Catholic charities Salvation Army etc.. no one has funds. If anyone can help in any way possible it would be a blessing an so greatly appreciated at this time we have nowhere to go.
